Multi-layered, thermally insulating covering envelope

ABSTRACT

A thermally insulating single or multipart multilayer covering jacket for covering a person, includes a body side and an outer side. The covering jacket contains a transfer layer, a blocking layer, and a storage layer arranged between the transfer layer and the blocking layer. The transfer layer is arranged so as to face the body side and is water-permeable in the direction of the storage layer and water-impermeable in the direction away from the storage layer. The blocking layer is arranged so as to face the outer side and is water-impermeable in the direction away from the storage layer, and the blocking layer forms an intermediate space for storing condensed water which is formed from the steam transferred into the storage layer through the transfer layer.

BACKGROUND OF THE INVENTION

Field of the Invention

The invention relates to the field of outdoor equipment, and primarilyconcerns a multi-layered, thermally insulating covering envelope forcovering a person and having a body side and an outer side.

Description of Related Art

Covering envelopes sometimes referred to as covering covers or coveringshells, serve for keeping people warm and, as the case may be, for theprotection from the influences of the weather when residing outdoors.Such weather influences can be wind, downpour, such as snow, hail orrain, as well as temperature conditions. Covering envelopes inparticular should keep sleeping persons sufficiently warm, be it duringan overnight stay outdoors or in buildings.

Covering envelopes according to definition can be covers, sleeping bagsor inlets. In contrast to a cover, the covering envelope of a sleepingbag forms a body receiving compartment that completely surrounds thebody to be kept warm.

Not only is the thermal management, thus the thermal insulation to theoutside important, but also the humidity or moisture management, foroptimal conditions. The danger of formation of condensation water existswith thermally well insulating covering envelopes, due to the fact thata person constantly releases moisture by way of transpiration. Theformation of condensation water is due to the temperature differencesbetween the body side of the covering envelope and the outer side of thecovering envelope.

The condensation water can form in the covering envelope itself, so thatthis becomes moist, or on the body of the person himself, depending onthe construction of the covering envelope. Such a formation of moistureleads to a reduction of the sleeping comfort and in the worst case to asevere cooling.

SUMMARY OF THE INVENTION

It is therefore an object of the invention, to create a coveringenvelope of the initially mentioned type, which is thermally wellinsulating and which permits the controlled leading of water vapour awayfrom the body region.

The covering envelope according to the invention is characterised by atransfer layer, a blocking layer and a storage layer, which is arrangedbetween the transfer layer and the blocking layer, wherein the transferlayer is arranged to the body side and is permeable to water vapour inthe direction of the storage layer and is impermeable to water in thedirection away from the storage layer, and the blocking layer isarranged to the outside and is impermeable to water in the directionaway from the storage layer. The storage layer forms an intermediatespace for storing condensation water formed from the water vapour, whichis led away from the body side through the transfer layer into thestorage layer.

The body side is that side of the covering envelope that faces theperson to be covered. The outer side is that side of the coveringenvelope that is away from the person to be covered. The outer sidefaces the outer environment.

The storage layer thus serves for storing the moisture that is led awayfrom the body side through the transfer layer. The water vapour, whichis led away from the body side through the transfer layer into thestorage layer, thereby condenses on account of the changed temperatureand humidity conditions in the storage layer.

The covering envelope in particular is designed such that the condensedmoisture can no longer escape from the storage layer without exposing(laying open) the storage layer. The storage layer is therefore alsotermed as a condensate trap, in which the condensed moisture is heldback. The storage layer accordingly forms a space for holding backcondensed water.

The comfort is retained to the fullest extent despite the formation ofcondensation water in the storage layer, since the construction of thecovering envelope does not permit a direct contact between the coveredperson and the storage layer.

The storage layer can include a moisture absorber that receives andbuffers moisture. Such a moisture absorber can, for example, be based onsilicate. The moisture absorber can, for example, be a silica gel.

The storage layer can include a material that creates a distance andthat creates or forms a cavity for receiving the condensed moisture. Thematerial creating the distance can be a spacer, such as a spacer fabric,a textile, a woven fabric, a net or foam material. Thedistance-creating, which is to say the space-creating material, inparticular is water-repellent, which is to say hydrophobic.

The space-creating material in particular is arranged between thetransfer layer and the blocking layer, or between a barrier layerdescribed further below and the blocking layer. The space-creatingmaterial can be attached to one or both of the mentioned layers, in adirect or indirect manner.

Spacer fabrics in particular are double-webbed textiles, with which thewarp-knitted fabric webs are kept at a distance by spacer connectionthreads, so called pile threads. The fabric webs in particular formplanes which are essentially parallel to one another. With regard to thespacer fabrics, it is particularly the case of meshed fabrics or knittedfabrics, which are expanded by a third dimension. The manufacture ofspacer fabrics, in particular is effected on double-bar Raschel machines(warp knitting looms) with two needle bars.

According to a further development of the invention, a spacer layerdistancing the transfer layer from the storage layer is arranged betweenthe transfer layer and the storage layer. The spacer layer in particularassists in leading water vapour away from the body side to the storagelayer.

The spacer layer can be a thermally insulating layer. The spacer layercan include an insulation material that creates a distance between thetransfer layer and the storage layer.

The spacer layer can also include a material that creates a distance andthat provides a cavity, in particular pores, for receiving air, thematerial having thermally insulating characteristics. The space-creatingmaterial can be a spacer body, such as a spacer fabric, a textile, awoven fabric, a net or a foam material. The construction of the spacerfabric is described in more detail further above. The space-creatingmaterial in particular is water-repellent or hydrophobic.

The spacer layer can also include hollow chambers fillable with air. Thedistance is achieved by the expansion, which is to say extension of thehollow chambers, which is effected by the air that is let into thechambers. The air in particular is compressed air. Chamber walls therebydelimit the extension of the spacer layer.

A barrier layer that is permeable to water vapour in the direction ofthe storage layer and is impermeable to water in the direction away fromthe storage layer can be arranged between the spacer layer and thestorage layer. The barrier layer ensures the transport of the watervapour through the spacer layer into the storage layer andsimultaneously prevents a penetration of moisture out of the storagelayer into the spacer layer.

According to a further development of the invention, the coveringenvelope on the side of the blocking layer that faces the outer sideincludes a thermally insulating layer. The thermally insulating layercan include an insulation material. The insulation layer serves for thethermal insulation of the body side.

The insulation material or the space-creating material, of theinsulation layers mentioned in this description in particular ishydrophobic. The insulation material can include a loose filling. Theloose filling can include down. The loose filling can include a plasticmaterial. The plastic material can include foam material parts, flakesor fibres.

The transfer layer can be permeable to water vapour in the directionaway from the storage layer. The transfer layer however can also beimpermeable to water vapour in the direction away from the storagelayer. The transfer layer can moreover also be permeable to water in thedirection of the storage layer.

The transfer layer in particular can be permeable to water vapour butimpermeable to water, in each case in both directions. The transferlayer in particular includes a membrane that is permeable to watervapour but is watertight. The transfer layer is thus breathable.

The membrane for this can include micro-pores that permit the passage ofwater vapour, but not drops of water. Such membranes are known forexample under the trademark names GoreTex® or eVent®.

The breathability of the membrane can also be achieved by hydrophilicmolecular components in an otherwise hydrophobic membrane. Suchmembranes are known for example under the trademark names Sympatex®.

The transfer layer can be an outer layer which faces the body side. Thetransfer layer can be embedded into a layer composite.

The blocking layer can likewise be impermeable to water in the directionof the storage layer. The blocking layer can be permeable to watervapour in the direction of the storage layer. The blocking layer,however, can also be impermeable to water vapour in the direction of thestorage layer.

The blocking layer can be permeable to water vapour in the directionaway from the storage layer. The blocking layer, however, can also beimpermeable to water vapour in the direction away from of the storagelayer.

The blocking layer in particular can be permeable to water vapour, butimpermeable to water, in each case in both directions. According to thisembodiment, the blocking layer can correspond to one of the membranesdescribed above.

The blocking layer can be designed as a foil. The blocking layer can beembedded into a layer composite.

A reflective layer that reflects infrared radiation to the body side canbe arranged between the storage layer and the body side of the coveringenvelope. The reflection layer can be a coating. The coating can be of ametal, such as aluminium. The coating can be effected, for example, byway of vapour deposition. The reflective layer can e.g. be deposited onthe transfer layer and face the body side.

The storage layer of the covering envelope, in particular, can beexposed in a reversible manner. “Can be exposed” means that a contactthat permits an efficient leading-away of moisture out of the storagelayer into the surrounding atmosphere is created between the storagelayer and the surrounding atmosphere. This means that the moisture doesnot need to pass all layers of the covering envelope, between thestorage layer and the body side or outer side.

Reversible means that the exposure, which is to say the laying-open,releasing, unravelling or unwrapping of the storage layer, can berendered reversible. Thus, the previously exposed storage layer assumesits function again as a condensate trap.

The condensation water that is formed in the storage layer can be ledaway to the outside in a direct manner in this way. This, for example,can be effected by way of dripping-off, shaking-out or by way of directevaporation into the surrounding atmosphere. The condensate that hasfrozen in the storage layer in the case of temperatures below freezingcan be led away by way of shaking it out. The condensate in particularcan be shaken out of a spacer fabric in the storage layer.

The exposure of the storage layer also permits the cleaning of this.

The covering envelope for this can include a reclosable opening, viawhich the storage layer can be exposed for drying and for cleaning asthe case may be.

The covering envelope can thus include a reclosable opening facing thebody side. This opening can lead through the transfer layer. Thecovering envelope can also include a reclosable opening which faces theouter side.

The opening in particular can be arranged in the region of a terminating(closure) corner or a terminating edge of the covering envelope.

The opening can, for example, be reclosable via closure means, such as azip closure or Velcro closure.

The opening, for example, can permit the storage layer to be turnedinside out.

The covering envelope can be single-part or multi-part, in particular oftwo parts. A multi-part covering envelope for example can be separatedinto at least two parts, in particular when laying open the storagelayer. This can be effected via a reclosable opening, which is mentionedabove.

The drying however can also be effected through the transfer layer tothe body side, in the case that this transfer layer is permeable towater vapour, in particular permeable to water and water vapour, in thedirection of the body side.

The drying can moreover also be effected through the blocking layer tothe outer side, in the case that this is blocking layer is permeable towater vapour, in particular permeable to water and water vapour, in thedirection of the outer side.

According to a further development of the invention, the coveringenvelope is designed of at least two parts. The at least two envelopeparts can be reversibly separated from one another, in particular alonga separating surface, for exposing the storage layer. The separatingsurface in particular runs parallel to the layers of the coveringenvelope.

The separating surface can lead through between the storage layer andthe blocking layer, so that the storage layer can release the moistureto the surroundings after the separation of the envelope parts.Accordingly, the storage layer remains completely in one of the envelopeparts.

The separating surface can also lead through the storage layer itself.This means that the storage layer is undone (separated open) onseparating the two envelope parts. The storage layer is accordinglyformed between two sides of the two envelope parts that face oneanother. The side can also be an outer side or inner side of theenvelope parts.

The covering envelope in particular is of limp nature and is notshape-stable.

The covering envelope can, for example, be designed and used such thatthis bears or lies on the body of a person in a direct manner onoperation.

The covering envelope can also be designed and used such that this onoperation forms a body receiving compartment, as described hereinafter,in the embodiment of a shape-retaining body receiving space, and inparticular no longer lies directly on the body of a person.

This, for example, can be achieved by way of the covering envelope beingshape-stable in operation. The covering envelope can therefore bebrought into a shape-retaining position via chambers that are fillablewith compressed air, or via a frame that is integrated into the coveringenvelope or one that is separate. The covering envelope can moreover bespanned out via a suitable spreading/spanning-out device.

According to a first embodiment, the covering envelope is a cover, byway of which a person can be covered. If the cover is of several parts,in particular of two parts, the separating surface in particular runsparallel to the layers of the cover. The cover in particular can bedivided into two part-covers. The part-covers in particular areconnected to one another along their edges.

According to a second embodiment, the covering envelope is an envelopebody that forms a body receiving compartment. The envelope body inparticular is of a limp nature.

The envelope body in particular forms a head opening, which represents aconnection from the body receiving compartment to the surroundings.

The envelope body moreover includes an access opening. This can beclosable, e.g. by way of a zip closure or Velcro closure. The access andhead opening can each be formed by separate openings. The access andhead openings can also form a common opening.

Such an envelope body can be designed, for example, as a sleeping bag orinlet (ticking), e.g. for a sleeping bag.

According to a particular embodiment variant of a multi-part coveringenvelope, the envelope body has an outer envelope that forms a receivingcompartment for an inner envelope.

The covering envelope moreover includes an inner envelope that can beremoved from the receiving compartment of the outer envelope and beinserted again and that forms the body receiving compartment. The innerenvelope in particular is constructed in a multi-layered manner. Theinner envelope that can be described as an inlet forms an inner sidethat faces the body receiving compartment, i.e. the body side. Thetransfer layer is arranged in the inner envelope.

According to a first further development of the invention, the outerenvelope is likewise part of the moisture management system according tothe invention and, for example, includes features according to theinvention, such as the storage layer and/or the blocking layer.

The moisture management system however can also be completelyaccommodated in the inner envelope. The inner envelope accordinglyincludes the transfer layer, the storage layer and the blocking layer.The outer envelope thereby in particular serves for thermal insulation.

According to a first further development, the separating surface canlead through the storage layer, as has already been discussed furtherabove. The storage layer is thereby formed between the outer side of theinner envelope that faces the outer envelope, and the inner side of theouter envelope that faces the inner envelope. This means that thestorage layer is formed between the inner envelope and the outerenvelope.

The separating surface, as already explained further above, can alsolead through between the storage layer and the blocking layer. Thestorage layer is accordingly part of the inner envelope. The blockinglayer in contrast is part of the outer envelope. The blocking layer inparticular can form the inner side of the outer envelope that faces theinner envelope.

The separating surface can moreover also lead between the blocking layerand the inner side of the outer envelope that faces the inner envelope.The storage layer and the blocking layer are accordingly part of theinner envelope. The blocking layer can form an outer side of the innerenvelope that faces the outer envelope.

According to a further development of the invention, the outer envelopeis designed in a multi-layered manner.

The outer envelope can include an outer layer that is directed away fromthe body receiving compartment, to the surroundings and that forms theouter side. The outer layer can be impermeable to water. The outer layercan be impermeable to water vapour.

The outer envelope can include a thermal insulation layer with aninsulation material, in particular of the already mentioned type.

The insulation layer can be arranged between two outer-lying layers thatform the outer side and inner side of the outer envelope. Theouter-lying layers can be impermeable to water in both directions. Theouter-lying layers can be impermeable to water vapour in bothdirections. According to this variant, the insulation layer is designedas an intermediate layer that is arranged between the two mentionedlayers.

If the inner envelope includes an outer layer facing the outer envelope,or the outer envelope includes an inner layer facing the inner envelope,the layers being water-tight or water-tight and water-vapour-tight, thenthe moisture in the storage layer cannot penetrate further outwards intothe outer envelope or into the insulation layer of the outer envelope.The moisture in contrast is held back in the storage layer of the innerenvelope or in the intermediate space between the inner envelope andouter envelope.

The outer envelope can also be constructed of several envelope parts, inthe manner of an onion skin. More or fewer envelope parts of the outerenvelope can therefore be used, depending on the weather conditions. Theenvelope parts for this are designed in a manner in which they areinsertable into one another and separable from one another again.

The inner envelope and the outer envelope can be releasably connected toone another in the operating condition via releasable connections, suchas Velcro connection, zip closure or push-button connection. The innerenvelope in particular can be completely separated from the outerenvelope.

The outer envelope can include a longitudinal closure arranged in thelongitudinal direction, for the length-side opening of the outerenvelope. The longitudinal closure on the one hand serves, e.g., forintroducing the inner envelope into the outer envelope and on the otherhand as an access opening.

The inner envelope can include a longitudinal closure arranged laterallyin the longitudinal direction, for the length-side opening of the bodyreceiving compartment. The longitudinal closure, e.g., serves as anaccess opening into the body receiving compartment.

The longitudinal closure can, for example, be a zip closure or a Velcroclosure.

The inner envelope can also be insertable into the outer envelope via anopening at the head-end side.

Moisture in the form of water vapour is then formed in the bodyreceiving compartment due to use. The envelope body is then designedsuch that this moisture is led from the body receiving space orcompartment, through the transfer layer of the inner envelope, into thestorage layer. The moisture condenses in the storage layer and is heldback.

The inner envelope is removed from the outer envelope and in particularis separated from this, for getting rid of the moisture from the storagelayer. The inner envelope and the outer envelope can then be driedseparately and cleaned as the case may be.

The outer envelope and, as the case may be, also the inner envelope canbe turned inside out if necessary for this.

The drying can be effected actively, (e.g. by way of a drying applianceor by way of shaking out) or passively (by way of hanging up, out in theopen). The dry outer and inner envelopes can then be brought togetherfor the next use.

According to a particular embodiment variant, the covering envelope canalso be the envelope body of a sleeping unit, the sleeping unit forminga body receiving compartment in the form of a shape-retaining bodyreceiving space. The envelope body can be self-supporting, andshape-stable. The body receiving space can be tunnel-like or tubular.The envelope body can be designed of at least two parts and include anouter and inner envelope, which is described above.

The sleeping unit in particular includes a base part. The base part canbe designed in a multi-walled manner with hollow chambers that lietherebetween and that are fillable with compressed air, for assuming amattress function.

The covering envelope can also be designed as a cover or inlet for asleeping unit, which is mentioned above.

FIGS. 3a, 3b, 4a, 4b , 5 and 6 show a covering envelope 80, which isdesigned as a sleeping bag. The covering envelope 80 is present as anenvelope body with a body receiving compartment.

The envelope body is likewise designed in a two-part manner and includesan outer envelope 86 and an inner envelope 82. The outer envelope 86 andthe inner envelope 82 in each case form a head opening 90. The outerenvelope 86 and the inner envelope 82 moreover each include a zipclosure 91, 92, which is arranged laterally in the longitudinaldirection, for opening the outer envelope 86 and the inner envelope 82respectively. The zip closure 91 in the outer envelope 86 on the onehand serves for introducing the inner envelope 82 into the outerenvelope 86 and on the other hand as an access opening. The zip closure92 in the inner envelope 86 serves as an access opening.

According to the two embodiments which are mentioned above, the innerenvelope 52, 82 is designed in a multi-layered manner. The innerenvelope 52, 82 includes a transfer layer 53, 83, which forms the innerside, thus faces the body receiving compartment 51, 81.
